AIR CIBCULATING AND HEATING APPARATUS.

Application filed November This invention relates to apparatus for circulating heated air and has particular reference to an apparatus which may be employed in cold weather as a heater and in warm weather for promoting the circulation of air in a room to cool the same.

ore specifically the invention comprehends a water-heated radiator in which water is heated and circulated by an electric heater and through which the air in a room is circulated to raise the temperature in the room to the proper degree. The invention further comprehends in an apparatus of the character set forth, means for rendering the radiator unit inactive whereby the device ma'y be employed for promoting circulation of the air in a room to agitate and cool the same.

' heating the water to cause The invention furthermore comprehends an apparatus of the character set forth which is comparatively simple in its construction, inexpensive to produce, economical to operate and which is highly eflicient in its purpose.

With the above recited and other objects in view, reference is had to the following specification and accompanying drawings in which there is exhibited one example or embodiment; of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understod that variations and modifications which properly fall within the scope of said claims may be resorted to when found expedient.

In the drawings-- Figure 1 is a sectional view taken approximately on the line -A--A of Fig. 2;

Fig. 2 is a side view with parts in section.

Referring to the drawings by characters of reference, the device preferably includes a casing 10 havin inlet ports 11 and a radiator unit 12 defining outlet openings 13. The radiator unit comprises a hollow body 14 throii h which air tubes 15 extend, said tubes def ii'ng the outlet openings 13. From a point adjacent its lower end, a water circulation pipe 16 extends upwardly to a point adjacent the top wall 17, the lower end of the pipe 16 havi aflared or enlarged intake 18 arrange over a well 19 and provided with a valve 20. An electric resistance heater 21 of an disposed immediately be ow the wel for an upward circuapproved t pe is g 22 1926. Serial No. 150,109.

lation of the same through the pipe 16 from whence it gravitates downwardly around the air tubes 15 to the bottom of the radiator unit. Within the casing 10, a device such as an electric fan 22 is mounted for drawing air through the inlet ports 11 and expelling the same through the air pipes 15 or outlet openings 13. The heat radiated from the heated water in the radiator unit serves to heat the air expelled through the outlet openings or air pipes 15 so that within a short length of time the temperature in the room in which the apparatus is arranged will be raised to the proper degree. he heating element and the fan are 'preferabl arranged in parallel in a circuit 23 whici includes a source of supply 24 and the conductors 25 which lead to the electric heater 21 have included therein a detachable plug element 26 which allows for the disconnection of the heater from/its source of supply when it is desired to use the apparatus as an air circulating In order to render the evice safe, the radiator unit isprovided with a safety valve 27 which is connected with a circuit breaker 28 in the circuit 23 for cutting off the electric heater 21 in event of an excessive heating of the water in the radiator unit either by virtue of failure of the fan to operate or for any other cause.

From the foregoing it will be seen that the. present invention embodies an electrically operated means for radiating heat and for circulating air through the heat enerated in the radiating means so as to eat the air for insuring a rise in temperature.

It is obvious that the device may include a thermostatic control, if desired, for automatically rendering the same active and inactive in accordance with the temperature desired.

What is claimed is:

1. An apparatus for circulating and heatmg air, inc uding a casing having air inlet and outlet ports, means within the casing for drawing in air throu h the inlet and expelling the same throug the outlet ports, and an electrically heated closed water radiator through which the heated water is circulated, having air passages therethrough, mounted in the outlet for radiating the heat to heat the air during its expulsion.

2. An apparatus for circulating and heating air including a casing having air inlet and outlet ports, means within'the casing or agitating means only.

for drawing in air through the inlet and expelling the same through the outlet ports, an electrically heated closed Water radiator through which the heated Water is circulateol, having air passages therethrough, mounted in the outlet for radiating heat to heat the air during its expulsion, and means for rendering the heat-radiating means inactive or to adapt the device as an air circulating means only. a r,

3. In an apparatus for effecting the circulation of air and heating thereot', a casing having inlet and outlet ports, a aterheated radiator framing the outlet, electrical means for heating and circulating the water in the radiator, and an electrically operated circulating means Within the casing for drawing in the air through the inlet and eX- pellingthe same through the outlet ports.

4.. In an apparatus for efiecting the circulation of air and heating thereof, a casing having inlet and outlet ports. a water-heated weenie radiator framing the outlet, electrical means for heating and circulating the Water in the radiator, and an electrically operated circulating means Within the casing for drawing in the air through the inlet and enpelling the same through the outlet ports, said water-heated radiator including a valved circulating means for augmenting the circulation of the water in the radiator,

5. In an apparatus for effecting the circulation of air and heating thereof, a casing having inlet and outlet ports, a water-heated radiator framing the outlet, electrical means for heating and circulating'the Water in the radiator, an electrically operated circulating means Within the casing for drawing in the air through the inlet and expelling the same through the outlet ports, a safety valve provided in the radiator, and means operated thereby for breaking the circuit of the electric-heating means.
